Used toner returnable 28 is arranged between fixing device 8 and image forming part 100, illustratedly transports path and transports means by not having, and used toner transports towards above-mentioned used toner returnable 28.Between fixing device 8 and used toner returnable 28, on diagram right side, quite locate configuration used heat fan 29.By this used heat fan 29, the air-flow being heated by heating (photographic fixing) roller 14, by above used toner returnable 28, prevents that used toner returnable is overheated.Used heat fan 29 has the function outside near heated Bas Discharged auto levelizer fixing device 8.
The detailed presentation video forming portion 100 of Fig. 3.In Fig. 3, photoreceptor 1 is towards diagram counterclockwise (direction of arrow) revolution.Around photoreceptor 1, along its gyratory directions, configuration cleaning balde 22, charging roller 2, and developing apparatus 3.
Developing apparatus 3 comprises that developer roll 7, the first transports spiral 41, and second transports spiral 42.First transports spiral 41 and second transports spiral 42 and is configured in developing apparatus 3.Cleaning balde 22 for reclaiming among the toner image being formed on photoreceptor 1, be not transferred in the remaining toner on paper P.The remaining toner being reclaimed by cleaning balde 22 scrapings, as used toner T, by toner, transporting spiral 24 is transported in path 25 and is not had, in illustrated path (used toner of Fig. 8 described later and Fig. 9 transports path 26), to be transported to used toner returnable 28 by toner.
In the present embodiment 1, used toner is recovered to used toner returnable 28, by the heat from fixing device 8, and the used toner that melting is reclaimed.But if image processing system PR becomes off-state, fixing device 8 becomes energising halted state, from the heating of fixing device 8, stop, fixing device 8 is cooling until room temperature.Thus, the used toner of melting solidifies.Like this, according to the connection of image processing system PR, disconnection, in used toner returnable 28, melting and curing repeatedly.
Therefore, toner is used following toner: toner constituent comprises the modified polyester resin that can react with the compound with reactive hydrogen base, this toner constituent is dissolved and/or is dispersed in organic solvent, make this lysate or dispersion in comprising the water-medium of resin particle, react and obtain with the compound with reactive hydrogen base, its toner adhesive, together with above-mentioned modified polyester resin, is used the low melt toner that contains crystalline polyester resin.By using this low melt toner, can be with low temperature heating and melting used toner.Thus, can carry out the melting of toner energy-conservationly and solidify.
In above-mentioned melting and curing repetitive process, if having illustrated used toner to be full of sensor, used toner in used toner returnable 28 do not detected and become and be full of, be illustrated in and do not have on illustrated guidance panel.Meanwhile, image processing system PR stops image and forms action.
After this, take out used toner returnable 28, discarded used toner, installs used toner returnable again, continues image and forms action.At this moment, because the used toner in used toner returnable 28 does not solidify, therefore, make it continue image form action if want, discardedization is time-consuming.If make, discarded do not change time-consumingly, need to prepare other used toner returnable 28 in advance, need to again install.
Recovery and the discarded example that thus, can carry out simply used toner are the following stated embodiment 2 to embodiment 7.
[embodiment 2]
Fig. 4 represents the image processing system PR that embodiment 2 relates to.In embodiment 2, in the image processing system PR of black and white, fixing device 8 is positioned at the top of image forming part 100, and recoverer B clips fixing device 8 with fusing department A and is set in upper and lower separated position.Used toner returnable 28 is arranged on respectively recoverer B and fusing department A.
Fig. 5 A and Fig. 5 B mean the stereographic map of formation of the used toner returnable 28 of embodiment 2.Being formed in embodiment 1 to embodiment 7 of used toner returnable 28 self is general.
The used toner returnable 28 that this example relates to is horizontally installed on fusing department A and recoverer B as mentioned above, is configured in this position.The upper and lower one side of used toner returnable 28 has thermal insulation, and another one side has thermotolerance.In the present embodiment, the face representing with oblique line surrounding with heavy line above of Fig. 5 A is the face 28a with thermal insulation, and the face representing with oblique line surrounding with thick dashed line below of Fig. 5 B is to have stable on heating 28b.
Used toner returnable 28 is when being arranged on recoverer B, and the face 28a with thermal insulation becomes and the heat source side of fixing device 8 side of joining.Thus, prevent the used toner T melting of recovery, and prevent the heat affecting image forming part 100 of fixing device 8.
On the other hand, when being arranged on fusing department A, the face 28a with thermal insulation becomes and the image forming part side of image forming part 100 side of joining.Thus, prevent from causing used toner melting because of the heat of the thermal source from fixing device 8, and prevent the heat affecting image forming part 100 of fixing device 8.Regardless of which kind of characteristic, all it doesn't matter in the side of used toner returnable 28, is made as in the present embodiment the face with thermal insulation.In Fig. 5 A and Fig. 5 B, what represent used toner returnable 28 has thermal insulation above, has a stable on heating example below.Above and there is which kind of function below and suitably set according to the configuration of fixing device 8.Even in following examples, the thick line of used toner returnable 28 part also represents to have the face 28a of thermal insulation.
As the material with the face 28a of thermal insulation, can use the polyfoam such as polystyrene foam etc., or the fiber-like thermal insulation material such as glass wool etc.The reason that makes it have thermal insulation is for the heat protection image forming part 100 for from fixing device 8, and in order to prevent used toner melting.
As the material with stable on heating 28b, can use such as polyamide or polyamidoimide etc.Make it have stable on heating reason and be and make used toner returnable 28 self not because hot impact is melted for the heat for from fixing device 8.
Used toner returnable 28 is located at occasion between image forming part 100 and fixing device 8, needs paper P can pass through the space of used toner returnable 28.Fig. 6 and Fig. 7 represent used toner returnable 28 correspondingly, and Fig. 6 is planimetric map, and Fig. 7 means the stereographic map with paper relation.From these figure, at the length direction central portion of used toner returnable 28, be provided with gap (spatial portion that width the is narrow) 28c that paper P can pass through.The cubic face of the above-mentioned gap 28c of used toner returnable 28 is separated and is arranged by wall, and the used toner T being recovered in used toner returnable 28 can not spill from this gap 28c.
Fig. 8, Fig. 9 A, Fig. 9 B, Figure 10 A, and Figure 10 B means the key diagram of the state of the used toner T being recovered in used toner returnable 28.
Used toner returnable 28 the used toner T of fusing department A melting, cooling rear solidify, therefore, can not be arranged on internal tank by transporting the such parts that transport of spiral.As shown in Figure 8, used toner transports path 26 and is connected with the bottom surface of used toner returnable 28.The used toner T being reclaimed by cleaning balde 22 transports path 25 through toner, transports path 26 discard in used toner returnable 28 from used toner.At this moment, if keep horizontality, used toner aggregation transports near the peristome in path 26 at used toner.Therefore, if do not impose countermeasure, between short-term in, used toner T is trapped near the peristome that used toner transports path 26, becomes and can not take in used toner.Fig. 8 represents used toner returnable 28 to be made as horizontality, represents that from used toner, transporting path 26 is transported to the state in used toner returnable 28 by used toner T.
So, in the present embodiment, as shown in Fig. 9 A and Fig. 9 B, when used toner returnable 28 is installed to recoverer B, setting is tilted used toner returnable 28, or as shown in Figure 10 A and Figure 10 B, the base plate of used toner returnable 28 is made as to dip plane.At this moment, the opening that makes used toner transport path 26 is positioned at the topmost of inclination.
If like this, the used toner T that the opening that transports path 26 from used toner is discarded in used toner returnable 28 disperses along inclined-plane to decline on one side on one side, is diffused into inclined-plane all.Its result, can reclaim used toner until capacity is reclaimed in the setting of used toner returnable 28.This is formed in following examples too.
Reclaim until reclaim after the used toner T cooling curing of the setting recovery capacity of used toner returnable 28.In order to make the recovery of this curing used toner Ta easy, also for example shown in Figure 11 A and Figure 1B, in used toner returnable 28, arrange and take out parts 28h.Taking out parts 28h consists of support plate 28i and functional unit 28j.Support plate 28i is under original state as shown in Figure 11 A, and the base plate 28k that is positioned at used toner returnable 28 is upper, and functional unit 28j connects the bottom that base plate 28k is projected into base plate 28k.If under this state, used toner T melting under full state, solidify, bulldozing operation parts 28j up as shown in Figure 11 B, thus, can, using curing used toner Ta as one, be easy to take out.This operates in while changing used toner returnable 28 and is carried out by user or attendant.
According to the present embodiment, used toner returnable 28 is configured in recoverer B, can be in the above and the isolated heat from fixing device 8 in side.Therefore, being accommodated in used toner T in used toner returnable 28 can melting, solidify, and can reclaim used toner.On the contrary, if used toner returnable 28 is configured in fusing department A, isolated heat below, therefore, can be in used toner returnable 28 internal causes the heat fusing used toner from fixing device 8.
Paper as shown in Figure 7, passes to upside from being located at the downside of the gap 28c of used toner returnable 28, is transported into fixing device 8.
If consider the recovery of curing used toner Ta or discard,, except structure shown in Figure 11 A and Figure 1B, can also use structure shown in Figure 12.Figure 12 means another routine stereographic map of used toner returnable 28.
Used toner returnable 28 shown in Figure 12 makes Fig. 5 A, and the used toner returnable 28 shown in Fig. 5 B and Fig. 6 is configured to and can opens up and down.That is, used toner returnable 28 consists of body 28e and cap 28f in this embodiment.At body 28e, be provided with handle 28d.Consider operability, handle 28d is made as and when used toner returnable 28 is arranged on to image processing system PR, is positioned at for example face side.
About the relation of body 28e and cap 28f, owing to taking out under used toner Ta melting, cooling curing state making, therefore, as long as both are in air-tight state, the depth relationship of body 28e and cap 28f is all right in any case.
If form the used toner returnable 28 that can open and close by body 28e and cap 28f like this,, when reclaiming, if open cap 28f, can easily take out used toner Ta curing in body 28e.
Figure 13 means the planimetric map of the another example of used toner returnable 28.
Used toner returnable 28 shown in Figure 13, at least one side of the used toner returnable 28 shown in Fig. 6, is in this case provided with the face of used heat fan 29 sides, and used heat fin 28g is set, and improves thermal diffusivity.Used heat fin 28g is set as easily by used heat fan 29, being discharged to shape and the configuration outside machine because of the air-flow of heating (photographic fixing) roller 14 heatings.Thus, can improve cooling effectiveness.By used heat fin 28g, increase area of dissipation, therefore, improve cooling effectiveness.Its result, can prevent that the temperature anomaly in image processing system PR from rising.Also used heat fin 28g can be located to upper and lower surface.
Figure 14 means the process flow diagram of the processing sequence that the melting and solidification (adding thermal thermocoagulation) of the used toner that the present embodiment is carried out is processed.
This processing is carried out by the CPU that there is no illustrated control circuit of image processing system PR.CPU comprises control part and operational part, the explanation of control part steering order and programmed control flow process, and operational part is carried out computing.Program is stored in does not have illustrated storer, and the instruction that should carry out (certain numerical value or numerical value are arranged) is taken out from the storer of said procedure is set, and carries out said procedure.
When be located at used toner returnable 28 do not have illustrated used toner to be full of detecting sensor used toner to be detected and be full of ("Yes" of step S101) time, although or be "No" at step S101, but when the guidance panel of never illustrated image processing system PR has the indication of implementation ("Yes" of step S102), start melting and solidification and process.
If start this processing, start the heating (step S103) of the well heater of heating (photographic fixing) roller 14, parallel therewith, start to drive the revolution (step S104) of heating (photographic fixing) roller 14.
Then, according to the detection output that there is no illustrated temperature sensor that is located at used toner returnable 28, if the temperature in the used toner returnable 28 detecting becomes 80 ℃ above ("Yes" of step S105), make 29 revolutions (step S106) of used heat fan.Thus, prevent that the excessive temperature in used toner returnable 28 from rising.If judge 80 ℃ of the temperature less thaies ("No" of step S105) in used toner returnable 28 in step S105, stop 29 revolutions (step S107) of used heat fan.
Then, if start through 10 minutes ("Yes" of step S108) from the well heater heating of step S103, stop well heater heating (step S109), also stop driving heating (photographic fixing) roller 14 (step S110), finish melting and solidification and process.
Like this, by used toner returnable 28 set temperature sensors, carry out above-mentioned control, heat the temperature of used toner returnable 28 until be suitable for the temperature of melting toner, can keep certain hour.Thus, melting used toner T, solidified in the cooling moment really.
Again, because heating (photographic fixing) roller 14 carries out after well heater heating at step S103, until stop well heater heating at step S109,14 revolutions of heating (photographic fixing) roller, the local pyrexia that therefore, can prevent heating (photographic fixing) roller 14 causes the distortion of roller or deteriorated.
Have, the melting and solidification of used toner T is processed when used toner is full of detecting sensor and used toner is detected and be full of ("Yes" of step S101) again, or when guidance panel has the indication of implementation ("Yes" of step S102) as triggering.Therefore, when used toner being full of to detecting sensor, used toner being detected and be full of as triggering and start to process occasion, in user's side, can judge the moment of changing used toner returnable 28.Again, automatically carry out the melting and solidification of used toner T and process, therefore, when carrying out this processing, can not bother user to operate.When user carries out and starts to process occasion as triggering from guidance panel indication, the reflection user meaning, the random time that user can change used toner returnable 28 in hope is carried out the melting and solidification of used toner and is processed.
Other does not have the part of special instruction identical with embodiment 1, has said function.
